Abstract: 342,770. Cam mechanism. BISHOP, R., 145, The Vale, Golder's Green, London. Nov. 8, 1929, No. 34118. [Class 80 (iii).] In cam gearing for use in steering mechanism of motor road vehicles and boats, throttle and ignition controls of internal-combustion engines, &c., a cam groove in a conical member 4 fixed on an operating- shaft 8 is engaged by a roller 20 or other part mounted on an arm 19 movable in a plane parallel to one edge of the cone about a driven rockershaft 1, the axes of the shafts 1, 8 being offset. The groove is produced (1) by subjecting the cam blank to the action of a fixed tool whose operative edge or face is at the same angle as the face of the roller, the blank being rotated on its axis and moved in the arc of a circle whose radius is equal to the effective length of the rocker-arm, the movement being effected without any change in direction of the longitudinal axis of the blank, or (2) by rotating the blank and moving the tool in relation thereto in the arc of a circle of the radius mentioned in (1). The roller arm 19 is so arranged that, as seen on a plane perpendicular to the shaft 1, the roller 20 twice crosses the axis of the shaft 8 in moving between its end positions. The shaft 8 carries a hardened bearing-washer 11 bearing on a similar washer 12 carried in the built-up casing 5. Specification 223,963, [Class 80 (iii), Linkwork &c.], is referred to.

[Also in Division E1] An aircraft fuselage 1 having, towards the front a station 2 for one or more pilots, comprises a fixed front window system 3 inclined at a large angle (e.g. line 65 at 45 Œ 5 degrees) to the fore-and-aft axis AA of the aircraft, a nose 5 forward of the fixed window system 3, and a single transparent shield 13 movable between a lowered position substantially within the nose and a raised position in front of the window system 3 (as shown) smoothly connecting the nose to the fuselage aft of the window system 3, the shield being inclined to the aircraft axis less steeply (e.g. line 63 at 20 Œ 2 degrees) than the fixed window system, and more steeply than either the nose, or the fuselage aft of the fixed window system (e.g. lines 62 and 64 each at 10 Œ 2 degrees). The nose 5 may be of elliptical cross-section (major axis horizontal and between 1.1 and 15 times the minor axis) and may be pivoted about axis 6 to be tilted down by 15 to 20 degrees for take-off &c. The shield 13 may be retracted by the retraction of a jack 22 causing an inverted A frame 15 to pivot about an axis 17 in the nose 5 moving point 18 on the shield which is also carried by roller assemblies 20 moving in fixed tracks 16 in the nose. The nose 5 may pivot about the axis 6 due to the extension of a screw-jack system 7, the nose having roller units 12 moving in fixed tracks 11 on the fuselage.

Title: Apparatus for demodulating a signal

Abstract: 1431952 Pulse modulation circuits PHYSICS INTERNATIONAL CO 1 June 1973 34123/75 Divided out of 1431951 Heading H4L Apparatus for demodulating a signal comprising a frequency burst of duration proportional to the amplitude of an analog signal, comprises rectifier means 86 (Fig. 11) followed by a filtering capacitor 87 and amplifying means 88 for producing an output signal of predetermined amplitude when a charge is stored in the capacitor above a minimum level, there being means Q24 for discharging the capacitor 87 to below the minimum to terminate the output signal when the duration-significant signal terminates, and means 89, 90 for integrating the output signal to produce an analog signal of amplitude proportional to the said duration. A central station addresses one of a plurality of remote stations which then sends to the central station a plurality of durationsignificant tones (of different frequencies) each representing the analog amplitude output of a respective sensor. A channel as in Fig. 11 is provided in the central station for each tone, the filter 84 separating it from the other tones. Fig. 6 shows part of the original modulation in a remote station for one sensor 20, the output of which is passed through an isolating amplifier 21 (with common-mode rejection) to a comparator 22 for comparison with a ramp. The ramp is produced by an integrator fed with a pulse produced in response to recognition of the station's address. The leading edge of this pulse also closes a switch 25 at Q10 to pass the output of an isolating amplifier following a tone generator, via relay contacts S1B. The switch 25 is opened to cut off the tone on comparator equality.

Abstract: 991, 506. Local circuits for magnetic recording heads. AMPLEX CORPORATION. Aug. 29, 1963 [Sept. 24, 1962], No. 34279/63. Heading G5R. [Also in Division H3] An oscillator-amplifier circuit for magnetic recording comprises an amplifying means having positive feedback means coupling the output circuit to the input circuit to cause the amplifying means to oscillate to produce a high frequency signal and to superimpose the high frequency signal on an intelligence signal applied to the input circuit of the amplifying means, and a magnetic head coupled to the output circuit of the amplifying means for receiving both signals. In Fig. 1 an input signal at terminal 27 is coupled to the grid of a valve 10 connected as a cathode-follower and feeding a magnetic recording head 29. The grid circuit also includes a tuned circuit including a tapped inductance 19 connected through a variable resistance to the junction of bias resistance 16 and load resistance 17. Inductance 19 acts as an autotransformer to introduce the positive feedback necessary for the circuit to oscillate and provide the high frequency bias for the recording head. In a modification, Fig. 2 (not shown), the input signals are amplified by a valve amplifier before passing to terminal 27. In further modifications, Figs. 3 and 4 (not shown), the valves are replaced by transistors.

[Also in Group XXIX] In a brake/unbrake selector valve for the hydraulic operation of reversible variable-pitch propellers comprising a movable member 4 having a centralizing spring 9 and providing connection between the coarse pitch line 5 and the fine pitch line 6 and the fluid pressure lines 2, 3 controlled from a constant speed unit, the movable member 4 contains spring-loaded balls 10 which will make latching engagement with a groove 13 in the wall of the valve chamber on displacement of the valve member 4 into its uppermost and blade pitch reversing position to hold the same latched until hydraulic pressure is applied to the member to move it towards its normal position. When, therefore, fluid pressure is applied to the line 7 the member 4 moves to, and is latched in, its upper position and fluid under maximum pressure from line 14 is applied to line 6 to move the pitch varying mechanism past fine pitch into reverse pitch position, the fluid in line 5 escaping through the core of the valve member to the return 15. To " unbrake " the propeller pressure is applied through the line 8 to overcome the action of the latching means 10, whereupon the spring 9 becomes effective to move the member 4 to its normal position.

[Class 40 (v)] The band-width occupied by a radio transmission is reduced by first separating the audio frequencies into high and low notes, using the low notes to modulate the carrier by the normal double side-band method, using the high notes to effect single side-band modulation, and radiating the combination. The low-note modulation is preferably of low percentage, and the single side-band carrying the high-note modulation is produced free of carrier wave and added to the former. The intensity of the high-note single side-band should be about double that of each low-note side-band. The characteristics of the filters used for separating the low and high notes should be such that their sloping flanks in the neighbourhood of the separating frequency compensate each other.
